The purpose of this article is to unravel the distinctions between these two primer varieties, clarifying their intended uses and helping you, the reloader, make an informed decision for your specific needs. We will delve into their characteristics, applications, and the factors that determine the best choice for your reloading endeavors.
Understanding Small Pistol Primers
Before we dive into the specifics of the Remington offerings, let’s establish a foundational understanding of what small pistol primers are in general. These are the tiny, yet critical, components nestled at the base of a pistol cartridge, essentially the heart of the fire.
Their primary function is to provide the initial spark that ignites the propellant, or gunpowder, contained within the cartridge case. This ignition generates a rapid expansion of gases, which pushes the bullet out of the barrel. Without a reliable primer, the firearm is rendered useless.
The anatomy of a primer is deceptively simple but meticulously engineered. It consists of a cup, an anvil, and a priming compound. The cup, typically made of brass or other alloys, houses the other components. The anvil is a small, internal piece against which the priming compound is crushed when struck by the firing pin. Finally, the priming compound itself is a carefully formulated explosive mixture, designed to detonate when subjected to a sufficient impact.
Small pistol primers are generally used in handgun cartridges designed for smaller-sized cases. Common calibers that utilize small pistol primers include the .380 ACP, 9mm Luger, .38 Special, and others of similar size and pressure requirements.
It’s important to understand the nature of primer sensitivity and the proper storage and handling. Primers are highly sensitive to impact, heat, and static electricity, so safe handling practices are paramount. They should always be stored in a cool, dry place, away from direct sunlight and excessive heat. Proper storage is essential to ensure their reliability and prevent premature detonation.

While suitable for the majority of pistol loads, the Remington Small Pistol Primer 1 1/2 might not be the best choice for magnum loads or those utilizing particularly hot powders or higher pressures. The difference lies in the ignition characteristics, which we will examine in the following sections.
Introducing Remington Small Pistol Primer 5 1/2
The Remington Small Pistol Primers 5 1/2 are specifically designed to deliver enhanced performance for the specialized demands of “magnum” pistol loads, and other high-pressure situations. The “magnum” designation indicates that these primers are built to withstand and effectively ignite the challenges of increased powder charges and higher pressures.
The design of the Remington Small Pistol Primers 5 1/2 differs from the 1 1/2 in ways that optimize their function for magnum loads. They may often feature a flatter cup and the priming compound could be formulated to offer a more aggressive ignition, igniting the powder more completely and consistently. This enhanced ignition is critical for achieving the desired performance when using magnum loads.
These primers find their ideal application in cartridges such as the .357 Magnum, and other high-pressure pistol loads. They provide the reliable ignition needed to fully burn the increased powder charges used in these rounds.
One of the key characteristics of the Remington Small Pistol Primers 5 1/2 is their ability to deliver consistent ignition even under challenging conditions. They offer a greater degree of brisance, or the shattering effect of the primer ignition, which can be essential for certain powder types or in colder weather conditions where reliable ignition is even more important.
These characteristics offer reloaders several key benefits. These primers are engineered for the challenging ignition requirements of magnum loads, enabling optimal performance. They are particularly useful when the cartridges might encounter conditions which can be difficult for traditional primer ignition.
The 5 1/2, due to their powerful ignition, may not be ideal in every standard load.
